Patent number: 8313830Abstract: Particle toughened, fiber-reinforced composites include a fiber region and an interlayer region between the fibers. The fiber region includes a plurality of fibers at least partially within a first polymer composition including a first base polymer formulation and a first plurality of toughening particles. The interlayer region includes a second polymer composition including a second base polymer formulation and at least one of the first plurality of toughening particles and a second plurality of toughening particles. Examples of first and second pluralities of toughening particles, respectively, may include core shell rubbers and polyimides. Increasing concentration of the first plurality of toughening particles may improve the composite toughness while preserving thermal properties of the composite, such as weight loss after extended duration exposure to elevated temperature.Type: GrantFiled: November 8, 2011Date of Patent: November 20, 2012Assignee: Cytec Technology Corp.Inventors: Mark Richard Bonneau, Jack Douglas Boyd, Gordon T. Emmerson, Scott D. Lucas, Stephen Jacob Howard, Spencer Donald Jacobs

Patent number: 8268926Abstract: Particle-toughened polymer compositions include a base polymer formulation and a plurality of toughening particles. In certain embodiments, the base polymer formulation includes bismaleimides or other polymer resins capable of high temperature service. A first plurality of toughening particles may include core shell rubbers. A second plurality of toughening particles may be selected from a variety of polymer compositions, including polyimides, polyether ketone (PEK), polyether ether ketone (PEEK), polyether ketone ketone (PEKK), polyether imide, polyether sulfones, and polyphenylene oxide. It is found that increasing concentration of the core shell rubbers may improve the toughness of the composition while preserving thermal properties of the composition, such as glass transition temperature.Type: GrantFiled: May 25, 2010Date of Patent: September 18, 2012Assignee: Cytec Technology Corp.Inventors: Mark Richard Bonneau, Jack Douglas Boyd, Gordon T.
